1 Built-in stereo speaker (left)
The stereo speakers are built into your computer.
For details, refer to the instructions in “Volume and mute buttons” on page 28.
2 USB connector (left)
The Universal Serial Bus (USB) connector is used for connecting USB interface-compatible devices, such
as a printer or digital camera.
Note: Your computer is compatible with USB 2.0.
3 Combo audio jack
Your computer has a combo audio jack. To listen to the sound from your computer, connect a headphone or
a headset, that has a 3.5 mm 4-pole plug, to the combo audio jack.
The combo audio jack does not support a conventional microphone. For more information about the audio
devices supported by the combo audio jack of your computer, see “Using audio features” on page 47.
Note: If you are using a headset with a function switch, for example, a headset for an iPhone ® mobile digital
device, do not press this switch while using the headset. If you press it, the headset microphone will be
disabled, and the internal microphone will be enabled instead.
4 Fan louvers
The internal fan and louvers enable air to circulate in the computer and cool the central processor.
Note: To avoid impeding airflow, do not place any obstacle in front of the fan.
